👉 The term "parallelepipedal" is often used in mathematics and physics to describe a 3-dimensional shape that has two parallel faces that are perpendicular to each other. This type of shape can be thought of as a prism with one base axis (parallel to the plane of the prism) and an additional base axis (perpendicular to the plane of the prism). The parallelepipedal is often used in geometry and solid mechanics to model objects like prisms, cylinders, cones, pyramids
